Description

Technical Field

[0001] The invention relates to the field of acrylic ball chamfering machines, in particular to a spherical acrylic polishing and chamfering machine. Background Art

[0002] Spherical acrylic needs to be polished to make its surface smooth after forming. In the prior art, the surface polishing process of spherical acrylic is generally done directly by manual polishing, so that the surface curvature uniformity and balance of the spherical acrylic after the batch polishing process is not consistent. When the curvature of the surface of the autumn acrylic is measured manually, there will always be deviations. In addition, since the surface of the spherical acrylic is gradually smoothed during the polishing process, the spherical acrylic at this stage cannot be clamped or placed in the prior art, which easily leads to the autumn acrylic falling off and uneven surface during the processing and polishing process. Summary of the invention

[0003] The invention provides a spherical acrylic polishing and chamfering machine, which overcomes the shortcomings described in the background technology.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A spherical acrylic polishing and chamfering machine comprises a chamfering machine body, a forming assembly and a processing base installed on the chamfering machine body, wherein the forming assembly is located above the processing base, and the processing base comprises a base and two driving members for driving the acrylic ball to rotate, wherein the driving members are symmetrically arranged on the sides of the base, the driving members penetrate into the base, and the driving directions of the two driving members are opposite;

[0006] The surface of the base has a placement groove for holding the acrylic ball, and the two driving members both pass through the placement groove. When the chamfer is processed, the acrylic ball is placed in the placement groove, and the two driving members are against the acrylic ball;

[0007] The driving member includes a second motor, a driving wheel, an adjusting belt, and a driven wheel. The driving wheel is mounted on the output shaft of the second motor. An opening for the adjusting belt to pass through is provided on the surface of the base. The driven wheel is rotatably mounted in the opening. The adjusting belt is sleeved on the driving wheel and the driven wheel.

[0008] The opening passes through the placement groove and is connected to the placement groove, and the adjustment belt protrudes from the surface of the placement groove and abuts against the acrylic ball contained in the placement groove;

[0009] The openings are symmetrically arranged on both sides of the placement groove, and the two openings are respectively connected to the left and right sides of the placement groove, and the heights of the two openings are staggered. The two adjustment belts inserted into the openings respectively abut against the surfaces of the acrylic ball at different heights, and the two adjustment belts are both arranged in an inclined state.

[0010] A preferred technical solution is that the second motor is fixed by a fixing frame, the second motor, the driving wheel and the driven wheel are all arranged in an inclined state, and the inclination angle is consistent with the inclination angle of the adjustment belt, and a mounting groove is provided in the opening, and the driven wheel is rotatably installed in the mounting groove.

[0011] A preferred technical solution, the molding assembly includes a limit rail body and a grinding assembly for grinding acrylic balls, the limit rail bodies are symmetrically arranged on both sides of the grinding assembly, the adjacent surfaces of the two limit rail bodies are each provided with a first slide rail, the first slide rail is provided with a first spring, the two ends of the grinding assembly are respectively embedded in the first slide rails of the limit rail bodies on both sides, and one end of the first spring is against the end of the first slide rail, and the other end is against the grinding assembly;

[0012] The first slide rail has an arc-shaped profile, and the first slide rail and the placement groove have the same center. When the grinding assembly is pushed to move, the grinding assembly swings with the center of the placement groove as the axis and compresses the first spring.

[0013] A preferred technical solution, the grinding assembly includes a first motor and a sliding adjustment member, a grinding head is installed on the output shaft of the first motor, the first motor is connected to the limit rail bodies on both sides through the sliding adjustment member, connecting shafts for embedding the first slide rail are provided on both sides of the sliding adjustment member, a second slide rail is provided on the side of the sliding adjustment member facing the first motor, and the first motor is embedded in the second slide rail through a connecting plate;

[0014] The second slide rail has an arc-shaped profile, and the second slide rail and the placement groove have the same center. When the first motor is pushed to slide along the second slide rail, the first motor swings with the center of the placement groove as the axis. A second spring is respectively provided at the corresponding positions of the second slide rail and the two sides of the connecting plate, and the two second springs are both against the connecting plate.

[0015] When the two second springs are not stressed, the first motor is perpendicular to the horizontal plane.

[0016] In a preferred technical solution, handles are symmetrically arranged on both sides of the first motor, one end of the handle is connected to the sliding adjustment member, and the other end extends over the side of the first motor away from the sliding adjustment member.

[0017] A preferred technical solution is that sandpaper is adhered to the lower end of the grinding head, and a groove concave inwards is provided at the corresponding position between the grinding head and the middle of the sandpaper, and a rubber elastic part is provided in the groove, and the rubber elastic part is against the middle of the inner side of the sandpaper.

[0018] Compared with the prior art, this technical solution has the following advantages:

[0019] During processing, the acrylic ball needs to be placed in the placement groove on the surface of the base to ensure stability during the processing. After starting the equipment, the two driving parts work at the same time. Since their transmission directions are opposite, the acrylic ball begins to rotate under the force in opposite directions. The rotating acrylic ball conflicts with the molding component, and the surface is polished and chamfered through friction and cutting. Since the two driving parts have opposite transmission directions, the acrylic ball can achieve full-range uniform rotation during the processing. This rotation method avoids the problem of uneven processing that may be caused by rotation in a single direction, ensuring that all parts of the spherical acrylic surface can receive the same polishing and chamfering treatment. The dual-drive design improves processing efficiency. In the same time, the spherical acrylic can complete more rotations, thereby increasing the number of contacts with the polishing wheel or chamfering tool, accelerating the processing process, and the two driving parts are symmetrically arranged and reversely driven, which helps to balance the vibration during the processing, reduce equipment wear, and improve processing accuracy and stability.

[0020] When the two second motors run at different speeds, they apply forces of different speeds and directions to the acrylic ball through their respective transmission system driving wheels, adjusting belts, and driven wheels. This speed difference and direction difference further enhances the multi-directional rolling characteristics of the ball, ensuring that all parts of the surface of the ball can be processed evenly.

[0021] Due to the arc design of the first slide rail, the grinding assembly will swing around the center of the placement groove as the axis when moving, so as to achieve fine control of the grinding effect. At the same time, the first motor can also perform more precise angle adjustments along the second slide rail on the sliding adjustment member to adapt to more complex grinding requirements. The second spring provides the necessary elastic support to ensure that the motor remains stable during the sliding process. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] like Figures 1 to 12As shown, the present invention proposes a spherical acrylic polishing and chamfering machine, including a chamfering machine body 1, a molding assembly 2 and a processing base 3 installed on the chamfering machine body 1, the molding assembly 2 is located above the processing base 3, and is characterized in that the processing base 3 includes a base 31 and two driving members 32 for driving the acrylic ball to rotate, the driving members 32 are symmetrically arranged on the side of the base 31, the driving members 32 penetrate into the base 31, and the driving directions of the two driving members 32 are opposite, the surface of the base 31 has a placement groove 311 for holding the acrylic ball, the two driving members 32 both penetrate the placement groove 311, when processing chamfering, the acrylic ball is placed in the placement groove 311, and the two driving members 32 are both against the acrylic ball;

[0043] During processing, the acrylic ball needs to be placed in the placement groove 311 on the surface of the base 31 to ensure stability during the processing. After starting the equipment, the two driving members 32 work at the same time. Since their transmission directions are opposite, the acrylic ball begins to rotate under the force in the opposite direction. The rotating acrylic ball conflicts with the molding component 2, and the surface is polished and chamfered through friction and cutting. Since the two driving members 32 have opposite transmission directions, the acrylic ball can achieve full-range uniform rotation during the processing. This rotation method avoids the problem of uneven processing that may be caused by rotation in a single direction, ensures that all parts of the spherical acrylic surface can receive the same polishing and chamfering treatment, and the dual-drive design improves processing efficiency. In the same time, the spherical acrylic can complete more rotations, thereby increasing the number of contacts with the polishing wheel or chamfering tool, accelerating the processing process, and the two driving members 32 are symmetrically arranged and reversely transmitted, which helps to balance the vibration during the processing, reduce equipment wear, and improve processing accuracy and stability.

[0044] The driving member 32 includes a second motor 321, a driving wheel 322, an adjusting belt 323, and a driven wheel 324. The driving wheel 322 is mounted on the output shaft of the second motor 321. An opening 312 is provided on the surface of the base 31 for the adjusting belt 323 to pass through. The driven wheel 324 is rotatably mounted in the opening 312. The adjusting belt 323 is sleeved on the driving wheel 322 and the driven wheel 324. The opening 312 passes through the placement slot 311 and is connected to the placement slot 311. The adjusting belt 323 The acrylic ball protrudes from the surface of the placement groove 311 and is pressed against the acrylic ball contained in the placement groove 311. When the second motor 321 is started, the driving wheel 322 starts to rotate and transmits power to the driven wheel 324 through the adjusting belt 323. Since the opening 312 passes through the placement groove 311, a part of the adjusting belt 323 protrudes from the surface of the placement groove 311 and directly presses against the acrylic ball contained in the placement groove. Therefore, when the adjusting belt 323 rotates, it will drive the acrylic ball to rotate together to achieve polishing and chamfering.

[0045] It should be explained that the output shafts of the two second motors 321 in the present invention have inconsistent rotation speeds. Different rotation speeds can be set as needed by independently controlling the two second motors 321. This design enables the two driving members 32 to rotate at different speeds, thereby generating a speed difference. Due to the existence of the speed difference, the spherical acrylic will begin to roll in a specific direction when subjected to two forces in opposite directions and at different speeds. This rolling method helps to achieve more comprehensive polishing and chamfering, because all parts of the sphere will contact the polishing wheel or chamfering tool. By adjusting the speed difference, the rolling trajectory and speed of the spherical acrylic can be accurately controlled, thereby achieving a more uniform and efficient processing effect, which not only improves the processing quality but also shortens the processing time.

[0046] Further, the openings 312 are symmetrically arranged on both sides of the placement groove 311, and the two openings 312 are respectively connected to the left and right sides of the placement groove 311, and the heights of the two openings 312 are staggered, and the two adjustment belts 323 inserted into the openings 312 are respectively abutted against the surfaces of the acrylic ball at different heights, and the two adjustment belts 323 are both arranged in an inclined shape, and the second motor 321 is fixed by a fixing frame 325, and the second motor 321, the driving wheel 322, and the driven wheel 324 are all arranged in an inclined shape, and the inclination angle is consistent with the inclination angle of the adjustment belt 323, and the opening 312 is provided with a mounting groove 314, and the driven wheel 324 is rotatably installed in the mounting groove 314;

[0047] As mentioned above, when the two openings 312 are staggered and cooperate with two second motors 321 with different rotation speeds, the processing effect of the spherical acrylic will be further improved. The following is a detailed analysis of the impact of this combination design:

[0048] Function of the staggered openings 312: As mentioned above, the staggered design of the two openings 312 enables the adjustment belt 323 to abut against different heights of the acrylic ball, which enables the ball to roll in multiple directions during processing, thereby achieving more comprehensive polishing and chamfering processing;

[0049] Synergistic effect of motors with different speeds: When the two second motors 321 run at different speeds, they apply forces of different speeds and directions to the acrylic ball through their respective transmission system driving wheel 322, adjusting belt 323, and driven wheel 324. This speed difference and direction difference further enhances the multi-directional rolling characteristics of the ball, ensuring that all parts of the surface of the ball can be evenly processed.

[0050] And the combination of two motors with different speeds enables the equipment to cope with more types of acrylic ball processing needs. Balls of different sizes, materials and shapes may require different processing parameters such as speed, pressure, etc., and this design provides a larger adjustment space to meet these needs.

[0051] Furthermore, the molding component 2 includes a limiting rail body 21 and a polishing component 22 for polishing the acrylic ball. The limiting rail body 21 is symmetrically arranged on both sides of the polishing component 22. The adjacent surfaces of the two limiting rail bodies 21 are provided with a first slide rail 211. The first slide rail 211 is provided with a first spring 212. The two ends of the polishing component 22 are respectively embedded in the first slide rails 211 of the limiting rail bodies 21 on both sides, and one end of the first spring 212 is against the end of the first slide rail 211, and the other end is against the polishing component 22. The first slide rail 211 has an arc-shaped profile, and the first slide rail 211 and the placement groove 311 have the same center. When the polishing component 22 is pushed to move When the grinding assembly 22 is swung with the center of the placement groove 311 as the axis, and the first spring 212 is squeezed, the output shaft of the first motor 221 is equipped with a grinding head 2211, and the grinding assembly 22 includes a first motor 221 and a sliding adjustment member 222, the first motor 221 is connected to the limit rail bodies 21 on both sides through the sliding adjustment member 222, and the two sides of the sliding adjustment member 222 are provided with connecting shafts 2223 for embedding the first slide rail 211, and the side of the sliding adjustment member 222 facing the first motor 221 is provided with a second slide rail 2221, and the first motor 221 is embedded in the second slide rail 2221 through a connecting plate 2212;

[0052] During operation, the operator can push the grinding assembly 22 to move on the first slide rail 211 as needed to change the contact point and grinding angle between the grinding head and the acrylic ball. Due to the arc design of the first slide rail 211, the grinding assembly will swing around the center of the placement groove 311 as the axis when moving, so as to achieve fine control of the grinding effect. At the same time, the first motor 221 can also perform finer angle adjustments along the second slide rail 2221 on the sliding adjustment member 222 to adapt to more complex grinding requirements. The second spring 2222 provides necessary elastic support to ensure that the motor remains stable during the sliding process.

[0053] The second slide rail 2221 has an arc-shaped profile, and the second slide rail 2221 and the placement groove 311 have the same center. When the first motor 221 is pushed to slide along the second slide rail 2221, the first motor 221 swings with the center of the placement groove 311 as the axis. A second spring 2222 is respectively provided at the corresponding positions on both sides of the second slide rail 2221 and the connecting plate 2212. The two second springs 2222 are both against the connecting plate 2212. When the two second springs 2222 are not subjected to force, the first motor 221 is perpendicular to the horizontal plane. Since this technical solution is different from the operation method in the prior art solution, it has a certain effect difference compared with the technical solution in the prior art.

[0054] For example, the adjustment range is large. Due to the arc design of the first slide rail, the grinding assembly can adjust the grinding position within a larger range and is suitable for workpieces of different sizes;

[0055] For example, grinding uniformity: the swinging grinding method helps to achieve uniform grinding effect and reduce the local over-grinding or under-grinding caused by fixed position grinding;

[0056] For example, the ability to quickly adjust the grinding position improves grinding efficiency, especially when processing multiple workpieces or different areas on the workpiece surface;

[0057] Under different working modes, the grinding component 22 achieves different grinding effects by adjusting the grinding position and angle. When moving on the first slide rail 211, it mainly focuses on quickly adjusting the grinding position and achieving grinding uniformity; while when sliding along the second slide rail 2221, it pays more attention to fine angle adjustment and improving grinding accuracy. These two working modes cooperate with each other, so that the grinding component can adapt to the grinding needs of workpieces of different sizes, shapes and surface requirements, and achieve efficient and high-quality grinding effects.

[0058] In addition, handles 223 are symmetrically provided on both sides of the first motor 221, one end of the handle 223 is connected to the sliding adjustment member 222, and the other end extends over the side of the first motor 221 away from the sliding adjustment member 222; the sandpaper 101 is adhered to the lower end of the grinding head 2211, and the corresponding part of the grinding head 2211 and the middle of the sandpaper 101 has an inwardly concave groove, and a rubber elastic part 102 is provided in the groove, and the rubber elastic part 102 is against the middle part of the inner side of the sandpaper 101, just like a small spring bed, which not only effectively fixes the position of the sandpaper, but also ensures the stability and durability of the sandpaper during the grinding process. This design method not only effectively fixes the position of the sandpaper to prevent it from falling off or moving during the grinding process, but also through the elastic support of the rubber elastic part, the sandpaper can better adapt to the slight changes on the surface of the workpiece, thereby improving the uniformity and fineness of the grinding.

[0059] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
